Hi Sasho,

Please say about its detection depth on a particular target.

Thanks in advance,

Hi Sasho
Thanks for your reply.

Hi Sasho
Sorry for my bad English ,
My opinion about PI long range locator , was two separate term.
First term about pulse induction and second was long range locator
Or LRL . for the first you did upload your P.I. circuit ,it is interesting
And I will study it.
Are you designing for second term , long range locator or LRL ?
Best regards .

Hi Sasho
Thanks again for your good PI circuit,
Please writing more about it.
Best regards .

Hi Aft,
Do you have made this PI?

[aft_72005]

Hi 1843
No,I study and check circuit theory, It is correct .
We are waiting Sasho more explain .

to Sasho

Hi Sasho,

Have you made this PI yourself?

[1843]

Hi Sasho
Please writing more about it.
Best regards .

This PI is not designed by Sasho. It is an old schematic with old parts...
Not used ICL7660, MOSFET, etc.

I am not inventor of warm water.Look integrator.This is my design.Schematic work perfectly.

Hi Sascho .
Do you remember the Tx pulse (us), the delay pulse(us) and the delay of sample1 and sample2(us).
Regards

tx-150.tx power max-250.delay1-30to130.delay2-50-450 microsec.

Hi 1843
PI was invented times ago. Designing based on our knowledge
And what’s we want.
Almost ,good designing not need modern and new parts .
At the end of project ,result very important. Good designing will
Has good result.
In my opinion all of Sascho designing was very good. I meet Sascho
And his circuits in this forum and don’t know him from later .
Also I simulate some parts of his circuits with proteus software .
All of those ,working very good in mathematics area.
For example push poll oscillator from TR circuit . at the first simulated ,
And second I built it in on breadboard .
Practical result seem as simulated result ,with good stability .

Hi Sascho
Please say me about deep of search on various type and size of metals.
Thanks a lot.

Hi again Sascho
And I have another question,
Are you have designing about LRL or long range locator ?
Best regards .
